DTC P0193 2005 Taurus, Where do we start to look.

you would have to connect a scan tool and see what the code is? That number P0??? will tell you the cause and from there how to fix.

P1237 - Fuel Pump Secondary Circuit Malfunction

Electronic Returnless Fuel Systems (ERFS) utilize a Fuel Pump Driver Module (FPDM) to control fuel pressure. The PCM uses a Fuel Rail Pressure Sensor (FRP) for feedback. The PCM outputs a duty cycle to the FPDM to maintain the desired fuel rail pressure. During normal operation, the PCM will output a FP duty cycle from 5% to 51%. The FPDM will run the fuel pump at twice this duty cycle, e.g. if the PCM outputs a 42% duty cycle, the FPDM will run the fuel pump at 84%. If the PCM outputs a 75% duty cycle, the FPDM will turn off the fuel pump.

If the FPDM does not out any diagnostic signal, (0 or 100% duty cycle), the PCM sets a P1233 DTC. This DTC is set if the FPDM loses power. This can also occur if the Inertia Fuel Switch is tripped.

If the FPDM outputs a 25% duty cycle, it means that the fuel pump control duty cycle is out of range. This may occurs if the FPDM does not receive a valid control duty cycle signal from the PCM. The FPDM will default to 100% duty cycle on the fuel pump control output. The PCM sets a P1235 DTC.

If the FPDM outputs a 75% duty cycle, it means that the FPDM has detected an open or short on the fuel pump control circuit. The PCM sets a P1237 DTC.


Keep us updated.

here are DTC codes for 93 taurus:

here are general ford P codes
http://www.svtlightnings.com/scantool/ford%20dtc%20codes.htm

Code P0316 means 'misfire detected first 1000 revs.'

Change plugs, and Mass Air Flow sensor. This should do the trick

have the timing checked.

change the coolant temp sensor and rest the codes then try
cleam the MAF by brake and parts cleaner

i hope its help thanx

I would think it would be just the Camshaft Position Sensor.I looked up the codes and they say pretty much the samething.
